TO ALL WHOM IT MAY CONCERN: l l

Be it'known that we, CHARLES Ross, Jr., and JOHN ROSS, of the city, county, and State of New York, have invented a new and useful Improvement in the FlueBru'sh; and we hereby declare that the following is a. full and exact description thereof. To enable others to make and use our invention, we'procced todescribe its construction and operation, reference being had to the annexed drawings, which make part of this speciiication Figure 1, the steel wires constituting the brush, set by casting metal round their bases.

Figure 2, end of the saine.

- I Figure 3, sniall brush with solid core. i

Figure 4, end of the same.

Figure 5, stem with one of the sections on it.

Figure 6, section shown cut in two.

Figure 7, the blank section.

Figure 8, that with cutters.

Figure 9, that with clusters of wires.l

Figure 10,-one of the halves'.

i The same letters referto the same things in all the designs.

A, the stern or rod by which the brush is operated. B, the wires of the brush. C, that part of the stem on which the sections or divisions of the brush are placed.l D, the solid core of the small brush. E, the nucleus or block of one of the sections. F, solid nucleus of the large brush. G, the blank. H, the cutter. I, the clustered brush. lThepurpose of this invention is to furnish to the fireman, or man in charge of a tubular boiler, an instrument withwhich he cancleanse out the foulest pipes, however long encruste'd. The flue brush for this purpose is necessarily various in size, in sti'ness, and in the combination of its parts. AA long irony rod is necessary in all cases, and it should have a loop or ring handle, or a bar like the handle of au auger. The stem that receives the sections that constitute the brush may be round,`or square, or hexagon. For all purposes it is best to be hexagon. The brush to be used is best made in parts or sections to put on the stem, and they should be in variety, so thatdiii'erent kinds may be united in the same brush, to be put on like washers in succession, though it may'be made in one piece, as in g. 1. The sections should be made of uniform thickness and to it the same stem,` and there should be blanks like washers to put on -to ll up. The blank sections having three or four holes from vperiphery to interior-larger inside or counter-sunk--may receive the wire 'clusters (put together as bristles are put in a brush) made of large or small wires, loosely' or tightly packed, secured in permanently or to set in as occasion may require, and foi` larger of smaller holes. In this case, having on hand the stem and blank sections, a brush can be extemporized for any size or pipes. When the clusters of wires .are put in from the inside, the bended paitconstituting a head, the clusters vwill be safely held when the section is put on the stem. The section E has the wires set evenly in all the periphery, (iig. 6.) The section I has'clusters set, iig. 9. `The section H has cuttersto cut into the pipe and loosen the scale by turning the instrument in, as an auger is made to bore in, (fig. 8.) The section G is a blank, and may receive clusters of wires or be used as a blank 'or washer. All 'these kinds or any of them can be` puton at once. .The knives of .the section H are set a little spirally so as to screw in. The half shown (iig. 10,) is aconvenient form to set the brush; bunches of wires being set in the holes, the two halves are coupled ou the stem, anda collar at each end makes all secure. When, the pipe to bve cleaned is small, and such a one as iig. 3 is to be used, the wires may be wound round in a spiral channel, that is, the spiral channel being made on a stem or stock, steel wires bent double are laid on the loop end, and as they are.laid a binding wire is drawn tightly round and holds them strongly in place, so that the wires will stand out pretty evenlyround the stem,but Ithis is intended for ilues not'requirin'g a `very stiff brush.

What we claim as our invention, and desire to secure by Letters Patent, is.-

1. The construction' of a brush for cleansing tubular boilers by` combining fused metal among wires, as in figs. 1 and 3, whereby to hold the wires of the brush riirm, substantially as set forth.

2. The arrangements of metal containing wires and cutters so as to form cutters and a section of brush, as shown at E, g's. 5 and 6, adapted to hc puton and oil, and of thc size to iit thc tubes to be cleansed, substantially in the manner and for the purpose as herein set forth.l
